William Henry McMaster was an American politician who served as the tenth Governor of South Dakota from 1921 until 1925. A member of the Republican Party, he went on to serve as a member of the United States Senate from South Dakota from 1925 to 1931.
The 1890 South Dakota gubernatorial election was held on November 4, 1890. Incumbent Republican Governor Arthur C. Mellette ran for re-election to a second term. He was challenged in the general election by State Surveyor General Maris Taylor, the Democratic nominee, and Henry A. Loucks, the President of the South Dakota Farmers' Alliance and the Independent Party nominee. In part because the left-leaning vote was split, Mellette won re-election, but by a significantly reduced margin, winning a weak plurality with just 44% of the vote. Loucks beat out Maris for second place, receiving 32% of the vote to Taylor's 24%.
The 1942 United States Senate election in South Dakota took place on November 3, 1942. Incumbent Democratic Senator William J. Bulow ran for re-election to a third term. During the primary, Bulow was attacked for being insufficiently supportive of President Franklin Roosevelt's foreign policy and war preparedness. Former Governor Tom Berry, Bulow's chief opponent, drew a contrast between Bulow's isolationism and his support for Roosevelt's policies. In the end, Berry defeated Bulow in a landslide, and advanced to the general election, where he faced Harlan J. Bushfield, the incumbent Republican Governor of South Dakota. As Republicans gained ground nationwide, Bushfield defeated Berry in a landslide to pick up the seat for the Republican Party. Bushfield did not serve his full term, however; shortly before the 1948 U.S. Senate election, he died.
The 1950 United States Senate election in South Dakota took place on November 7, 1950. Incumbent Republican senator Chan Gurney ran for re-election to a third term. He was challenged in the Republican primary by Congressman Francis H. Case, who had represented the 2nd District since 1939. In the general election, Case faced John A. Engel, an attorney and the 1948 Democratic nominee for the U.S. Senate. As the Republican Party was making significant gains nationwide, Case defeated Engel in a landslide.

He defeated former Governor Frank M. Byrne in the Republican primary and then faced former State Representative Orville Rinehart, the 1916 Democratic nominee for Governor, in the general election. Sterling defeated Rinehart, along with independent candidate W. T. Rafferty, by a wide margin to win re-election.
The 1920 United States Senate election in South Dakota took place on November 2, 1926. Incumbent Republican Senator Peter Norbeck ran for re-election to a second term. In the Republican primary, he faced former State Senator George J. Danforth, who had the support of Governor Carl Gunderson in an intra-party split between Norbeck and Gunderson. Norbeck defeated Danforth by a wide margin, and then faced former State Representative Charles J. Gunderson in the general election. Norbeck defeated Gunderson in a landslide to win re-election.
The 1930 United States Senate election in South Dakota took place on November 4, 1930. Incumbent Republican Senator William H. McMaster ran for re-election to a second term. After beating back a challenge in the Republican primary from former State Senator George J. Danforth, McMaster faced Democratic nominee William J. Bulow, the incumbent Governor, in the general election. As the Democratic Party performed well nationwide, Bulow narrowly defeated McMaster.
The 1936 United States Senate election in South Dakota took place on November 3, 1936. Incumbent Democratic Senator William J. Bulow ran for re-election to a second term. He was challenged by businessman Chan Gurney, who defeated former Congressman Charles A. Christopherson in the Republican primary. Bulow, likely aided by President Franklin D. Roosevelt's landslide victory in South Dakota, narrowly defeated Gurney to win his second term, though he significantly underperformed Roosevelt.
The 1954 United States Senate election in South Dakota took place on November 2, 1954. Incumbent Republican Senator Karl E. Mundt ran for re-election to his second term.

He won the Republican primary against Attorney General A. C. Miller, but shortly after the primary, died. The Republican State Central Committee named Lieutenant Governor Joseph H. Bottum as Case's replacement on the ballot, and Governor Archie Gubbrud appointed Bottum to fill the vacancy caused by Case's death. In the general election, Bottum was opposed by Democratic nominee George McGovern, the Director of Food for Peace and the former U.S. Congressman from South Dakota's 1st congressional district. The contest between Bottum and McGovern was quite close, with McGovern narrowly defeating him for re-election by just 597 votes, making him the first Democrat to win a Senate election in South Dakota since William J. Bulow's win in 1936.
The 1908 South Dakota gubernatorial election was held on November 3, 1908. Incumbent Republican Governor Coe I. Crawford opted to run for the U.S. Senate rather than run for re-election. State Senator Robert S. Vessey narrowly won the Republican primary over former State Representative John L. Browne and advanced to the general election, where he faced the Democratic nominee, former Governor Andrew E. Lee. Though Vessey's performance was significantly reduced from Crawford's performance in 1906, he still defeated Lee by a wide margin.
The 1912 South Dakota gubernatorial election was held on November 5, 1912. Incumbent Republican Governor Robert S. Vessey declined to run for re-election to a third term. Lieutenant Governor Frank M. Byrne won the Republican primary to succeed Vessey, and then faced State Senator Edwin S. Johnson, the Democratic nominee, in the general election. Byrne only narrowly defeated Johnson, winning just 49% of the vote to Johnson's 46%, the closest gubernatorial election since 1898.
The 1948 South Dakota gubernatorial election was held on November 2, 1948. Incumbent Republican Governor George T. Mickelson ran for re-election to a second term. He was opposed by Democrat Harold J. Volz, a businessman and the former Chairman of the Tripp County Democratic Party. Both Mickelson and Volz were the only candidates of their parties to file for Governor, ensuring that they won their respective nominations unopposed and removing the race from the primary ballot. In the general election, Mickelson had little difficulty defeating Volz. Though Republican presidential nominee Thomas E. Dewey only narrowly won the state over President Harry S. Truman, Mickelson's popularity allowed him to win re-election in a landslide, receiving 61% of the vote to Volz's 39%.
The 1938 United States Senate elections in South Dakota took place on November 8, 1938. Incumbent Republican Senator Peter Norbeck died in office on December 20, 1936. Herbert E. Hitchcock was appointed by Governor Tom Berry as Norbeck's replacement. Two elections for the same Senate seat were held on the same day; one as a special election to fill the remainder of Norbeck's six-year term, and another to select a Senator to serve the next six-year term.
The 1920 South Dakota gubernatorial election was held on November 2, 1920. Incumbent Republican Governor Peter Norbeck declined to run for re-election, instead choosing to run for the U.S. Senate.

Howes, the Democratic nominee. The election was largely a replay of the 1918 election, with McMaster winning a large victory, Bates coming in second, and Howes coming in a distant third.
The 1924 South Dakota gubernatorial election was held on November 4, 1924. Incumbent Republican Governor William H. McMaster declined to run for re-election to a third term, instead opting to run for the U.S. Senate. Lieutenant Governor Carl Gunderson won the Republican primary unopposed. In the general election, he faced three prominent opponents: Democratic nominee William J. Bulow, a former State Senator and Mayor of Beresford; Farmer–Labor nominee A. L. Putnam; and perennial candidate Richard O. Richards. Gunderson. With the left-leaning vote split, Gunderson won the election in a landslide.
The 1928 South Dakota gubernatorial election was held on November 6, 1928. Incumbent Democratic Governor William J. Bulow ran for re-election to a second term. In the general election, he faced Attorney General Buell F. Jones, the Republican nominee. Despite Republican presidential nominee Herbert Hoover overwhelmingly defeating Democratic nominee Al Smith overwhelmingly in South Dakota, Bulow defeated Jones by a decisive margin to retain the governorship. In so doing, he became the first Democratic candidate for Governor to receive a majority of the vote in the state's history.
The 1930 South Dakota gubernatorial election was held on November 4, 1930. Incumbent Democratic Governor William J. Bulow declined to run for re-election to a third term, instead opting to successfully run for the U.S. Senate. The Republican nomination was hard-fought and the primary was crowded; because no candidate received 35% of the vote, state law required that the nomination be decided at a state party convention. There, former State Senator Warren Green, the last-place finisher in the primary, defeated Secretary of State Gladys Pyle, the plurality winner. In the general election, Green faced D. A. McCullough, the state's Rural Credits Commissioner and the Democratic nominee. Despite Bulow's success in the preceding two elections, Green defeated McCullough by a decisive margin—even as Bulow himself was elected to the U.S. Senate.
The 1934 South Dakota gubernatorial election was held on November 6, 1934. Incumbent Democratic Governor Tom Berry ran for re-election to a second term. After defeating an intra-party challenge from Lieutenant Governor Hans Ustrud, Berry faced magazine publisher William C. Allen, who won a crowded Republican primary with a large plurality. Aided by the national environment favoring Democrats, Berry won re-election in a landslide.
The 1938 South Dakota gubernatorial election was held on November 8, 1938. Incumbent Republican Governor Leslie Jensen declined to seek re-election and instead unsuccessfully ran for the U.S. Senate. Harlan J. Bushfield, the former Chairman of the South Dakota Republican Party, won the Republican primary to succeed Jensen. In the general election, he faced Democratic nominee Oscar Fosheim, a State Representative from Miner County, in the general election. Bushfield defeated Fosheim by a relatively close margin, winning his first term as governor.
